87-244 25 mm Dia. Hard Coated Tri-Band Fluorescence Bandpass Filter; t=2 mm 432/517/615nm
The 87-244 is a high-quality Tri-Band Fluorescence Bandpass Filter, sourced from the renowned optical vendor, Edmund Optics. This filter is designed with a circular shape, featuring a diameter of 25 mm and a thickness of 2 mm, making it suitable for a wide range of optical applications.
The filter is specifically designed to transmit light at three distinct wavelengths: 432nm, 517nm, and 615nm. This is achieved through the use of a specialized coating, denoted as 'edm 87-236' on both the front and back surfaces. This coating ensures a high transmission rate for the specified wavelengths, while effectively blocking out other wavelengths.
The physical data of the filter includes a cut-on wavelength of 414nm and a cut-off wavelength of 450nm for the 432nm band. This indicates that the filter begins to transmit light at 414nm and stops transmitting at 450nm, with the peak transmission at 432nm.
The filter is made from UVFS Mal-1965 material, a robust and reliable option for optical filters. The 'Thin Lens' shape of the filter ensures easy integration into optical systems.
The filter is currently in stock and can be purchased directly from the Edmund Optics website, with the catalog number 87-244. The link to the product page is provided for your convenience.
